1086 dash

looked at a 1086 today and the digital part of the dash does not work. hour meter shows 3544 but pretty sure that aint correct. the ta don"t work either. what is the cost to fix the dash any idea? I need to call the previous owner about the tractor before I would buy it, but love the cab even though it needs a kit. much quieter than the 1066 with a year around on it with oil that is perfectly clean.

You are dealing with old technology. I wouldn't touch it unless I talked to that owner. You need to know if it was abused. If you can find out who it is drive by their place and see what their other machines look like.

1086 was our first tractor with a/c and duals. I thought I was in hog heaven. Loved that tractor but mainly because of the step up. Our 856 and 966 were more bulletproof.

How to fix 86 series dash: mount 2x4 at comfortable eye level behind steering wheel. Paint board to desired color. Mount after market tach, oil pressure gauge, water temp gauge, volt and/or ammeter depending on personal preference!

If the digital display on the tach is acting up these people can help: http://www.agexpress.com/ Senders have to work and some have to even be set properly for it to function correctly, too. At least two types of digital data centers were used.

The gauges are another story. They weren't great from the factory, and cost an arm and a leg to replace with the original style. They're either AC or Stewart Warner, or maybe the originals were one and the replacements the other, and aren't available from any aftermarket source. Start troubleshooting, or find someone who can. Senders need to be functioning for these to work, too. Mechanical or electronic gauges done tastefully and in a "do no harm/easily removable fashion are an option as well.

Mine has the all-analog dash; are those gauges still available? Thanks.

I may be confusing people so I'll expand on this.

Some came with a mechanical tachometer with the knob in the center like the -66 series.
Some came with a round digital tach/speedo assembly.
Some came with a rectangular digital tach/speedo assembly.
There was also a later digital one that could sense EGT as well.

I'm pretty sure at one time, IH renewed tachs were available for the round and rectangular (Newport?) digital units. I'm pretty sure as well they quit offering new rectangular units and may have even quit offering renewed ones and recommended the rectangular unit be replaced with the later one that could sense EGT. This type has some settings that have to be done based on tractor application, tire size, etc., as it is for multiple applications. The senders/transducers/pyro thermocouple should still be available.

The mechanical, cable-driven tachometer should still be available, along with the cable, either from CIH or perhaps from an aftermarket source.

I could be wrong, but I think the gauge panel was the same with all of these. 4 non-mechanical/electric gauges with dial faces: oil press., fuel level, voltmeter, and temperature, inside of a panel that also included the idiot lights. Those 4 gauges should all still be available, along with all of the senders.

'd be a little leery of this tractor if it's in the shape you describe. Sounds to me like they keep running their machinery after something breaks. Unless you want this tractor real bad, you might be better off walking away. I do have a few pointers for you concerning the tach. My 1086 has 16500 hours and I bought it new so I've had to figure out a few dash problems through the years.

The tach problem might not be all that bad. Do you know if the tach lights up at all? If it doesn't light up it might be the oil pressure activated switch on the right rear side of the engine just in front of the cab if it's an earlier one. The later 1086's had the tach come on when the key switch was turned on instead of the oil switch doing the job but I don't know how the newer ones are wired. If it lights up but reads zeroes, there's a speed sensor in the bell housing I think in front of the cab on the right side. That sensor might be bad or disconnected or out of adjustment. Or there might be a rat chewed wire somewhere too.

My 1086 is an early 1978 with the oil pressure activated tach switch. I finally got tired of the switch going bad and connected the two wires together and then went under the dash and moved the power feed from constant power to switched power. If I remember right it's all done in front of your feet.

You might want to get a quote on the TA before you start dickering price. There are still some pretty good 1086's lurking out there. Of course you never know when the TA will give up the ghost. Jim

Very helpful, thank you!
